FAN-FRAME FOR MlLLSTONE-CURBS.

SPECIFICATION forming part of Letters Patent No. 242,294, dated May 31, 1881,

Application filed April 12, 1881. (No model.)

To all whom it may concern:

Be it known that I, HARMON H. FULTON, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Improvement in Skeleton-Frames for Supporting a Fan-Shaft, Fan, and Fan-Box, of which the following is a specification.

My invention relates to improvements in the construction of a frame for supporting a fan, fan-shaft, and fan-box on the curbs of millstones, and the objects of my improvements are, first, to provide a light, strong, and durable frame for supporting the fan, fan-box, and shaft; second, to provide the frame with stationary studs for securing the same to the curb ofa millstone, and, third, to provide the frame with a step-box for supporting the lower end of the fan-shaft and holding oil for lubricating it. These objects I accomplish by the device illustrated in the accompanying drawings, in which- Figurel represents a vertical sectional view of the entire device, and Fig. 2 is a plan view of the base-frame.

Similar letters in the two views refer tolike parts.

A A A A represent the arms of the baseframe. The arms A A have at their outer ends upward-projecting arms I) b, to which the curved bar B is made fast by rivets or bolts (1 d. The upper central portion of the bar B is provided with a round hole and has the boss E secured to its upper side, as shown. The central part of the spider or base-frame A A is provided with a hole, at, immediately under the hole in the bar B, in which the shaft D is inserted and operates.

To the lower side of the frame AA A A is secured by the bolts to a the pendent step-box G, with a recess, a, in the center of the cup at for the lower end of the shaft D to operate in. The cup at is for the purpose of holding oil to lubricate the lower end of the shaft. The intervening space between the top of the oil-cup m and bottom of the frame A is for the pulley F, which is keyed or made fast to the fanshaft D, and is driven by a belt from a pulley attachedtotherunning-stoneofthemill. (Not shown.) The arms A A A A of the frame have studs 0 c projecting downward for securing the frame to the curb of a mill.

What I claim as new, and desire to secure by Letters Patent, is

A fan-frame for the curb of a millstone, consisting of the base-frame A A A A, the arms A A having upwardly-projecting ends I) b, and each arm provided with a downwardly-projecting stud 0, combined with the pendent I step-box 0 below, having oil-cup m and recess a for the shaft D, the metal bar B above, secured to the arms b I) and provided with a hole in its top, and the boss E and the fan-shaft D, all constructed and combined substantially as shown and described.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.

HARMON H. FULTON.
